Lenovo T400 / T500 :: No On Screen Display Of Caps Lock / Volume / Screen Brightness
May 27, 2014
I updated the BIOS to 2.26 a while ago and ever since then there's no on-screen indication of caps lock on/off, screen brightness or volume when I change it. Since it seemed to be affected by BIOS, I updated again to 2.27 just now, but the problem persists. I needed to update the Hotkeys Feature Integration by downloading the utility thingy from this page. Probably wasn't a BIOS thing after all.
I have a 3-yr old Thinkpad T500 laptop w/ XP. My on-screen volume and brightness displays have recently disappeared. Spoke with customer support and was advised to download all the machine updates....did that, but still not working.
I am currently stumped on troubleshooting error code lights for a clients hp compaq cq62. I have tried the hard reset, reseating the memory, and even plugging the notebook directly into the wall instead of a surge protector with the battery removed. I cannot find any solution on the HP site or any other forum site for that matter as to what a solid caps lock light and a solid orange light on the f12 key.
Currently I am thinking the client is might need a new back light for the system or a new cpu.
I can't adjust my screen brightness using the Power Manager. Updating to the latest release of the ThinkVantage Communications Utility did not solve the issue. I can't make the screen either brighter or dimmer.
My T440p slightly adjusts the screen brightness depending on what is being displayed. For example, on Chrome, one page might have more images, so the screen slightly adjusts brighter or darker. Another page it might slightly adjust again. And it does it when scrolling down a page as well. It is distracting, and I want to disable it? I'm on windows 7.
The company I work for just gave me a new Thinkpad T440P and I have a screen Brightness problem. the shortcuts on the keyboard doesn't work with or without the fn button and the brightness gauge doesn't show up in the power options too.
Someone suggested to that I should download and install the latest Intel HD Graphics Driver for Windows 7 from the support page [URL] ... but after the installation ended a pop up on my screen said that my Laptop doesn't have the minimum requirements for this driver! so who come it's in the drivers section for this model?
Every time I press caps lock, change volume i got a notification pops up that often messes up the window focus. It's particularly annoying when trying to play games. Can I turn this off?
I searched around for other people having the same problem and the one solution I got was to change Hkey_Local_MachineSoftwareWidcommBTConfigGeneral KeyIndication to 0, but that's already set to 0 for me, and I'm still getting notifications. The solution with removing "lockkey.exe" is not working as well. I just don't have program like this.
Got windows 7 on my g555, with truecrypt on the drive, if it matters. Last night, closed down the cover of my laptop before i fell asleep, like always, today it doesn't respond at all when I opened it back up. Forced it to shut down, and haven't seen anything but a black screen since.
The power light comes on, the fan comes on, and that's about it. Can't get to the bios, can't do ANYTHING. Tried unplugging it for a while, pressing power 10 times, holding power down for a minute, ran the battery entirely dry THEN discharged the caps, ...I've read many solutions where its the built up static charge that's the problem, but not here. I've tried all versions of the solution I could find, all very similar, but none worked. I took out my RAM and put it back in, and same for the hard drive. No dice.
The only lights I get at all are the power light, and the battery charging light next to it. Can't get the CAPS LOCK, num lock, any of that to do anything. Cannot boot by CD/DVD as I cannot change the bios, and can't get any response from any keys or key combos that I can think of (including the one-touch restore).
I rarely use this machine but a couple of months ago I went to boot it up and found that I was not able to get past the Windows splash screen. Sometimes I don't even get the Windows splash screen, I just get a black screen. Rarely I get a Windows screen saying that it is diagnosing a system problem or something to that effect and I can even get to where it will allow me to do some Windows diagnostics but nothing ever comes of it and the process is extremely slow.
I called Lenovo, but of course my machine is out of waranty so the tech just gave me a few pointers and said I could send it in to the depo but the potential repair cost could range up to about 75% of what I paid for the machine in the first place. Anyways, after having me try a few things in the BIOS he suggested that it was likely the hard drive. I mistakenly thought from the time that I bought this machine that the OS was installed on the 24 GB SSD so I ordered a new SSD and swapped it in. This made no difference at all as I have now learned that the mSATA SSD drive is merely for cache to speed up booting.
I am afraid that this means the main HDD is at fault, and quite frankly, if I replace it I am going to do a fresh install of Windows 7. But I do have pictures and docs that I would like to salvage if possible.
I am quite bugged by the Caps Lock onscreen display, since I cannot find a way to only turn off the capslock display without turning off all displays.
This display drops my FPS from about 70 to 40 when I'm playing video games which is bugging me a lot. But I would like to keep my other displays like soundlevel and screen brightness.
And yes, I know that it is possible to keep the capslock display for only 3 seconds when turning it on too, but I want it to be not displayed at all. I have a green light on my keyboard which is good for me.
So is it possible to completely turn off the capslock display without turning off the other displays?
I purchased an HP g62 notebook 2/12yrs ago I have not used it for almost a year. Problem it is having at first it was not charging properly I would get a message about battery being low and may need to be replaced I continued using it like that for like a month then one day I went to start it up this is what I got' blank screen,caps lock bli king 6 times then blink another 3 times then 6 times then 3 times repeated while the internet button is orange. The fan runs the CD opens, I just replaced the battery and new charger.
I have an HP g6-1325sa had an issue that had to replace the fan. However since then nothing will appear on the screen F12 has an orange light on and the caps lock continuously flashes every 2-3 seconds. This is not a blink code it does this continuously.So far i have tried blocking the vents and leaving the laptop running for over an hour as I heard it can be caused by dry solder joints.
I have also tried replacing the motherboard and have twice managed to get a cursor flashing on the screen however niether of these times could a normal boot happen as the HDD was disconnected on both of these occassions, the first time this happened i had just disconnected power and battery and held down power for 30 seconds, i'm guessing that was a cmos reset.
The only cause i can think of is that the processor was cooked when the fan was replaced but having already paid for another motherboard i'd like someone to confirm what it means when the caps lock blinks endlessly and if there is another way to repair it.
I have a 1 year old inspiron 1520 laptop which has suddenly stopped working.
When I press the power button, the power light comes on but I don't hear a fan whirring, the battery light also comes on. The screen is totally blank and the caps lock icon continually flashes and after about a minute the computer shuts down.
This happens with the battery attached or connected to the mains.
I have a major problem with my hp pavilion dv6-3143sa laptop.
I put it to a shop and they told me it was a motherboard/cpu problem and they couldn't source parts. I managed to get the parts. I put the motherboard first, but didn't work. I then added the cpu and put on thermal paste, but still didn't work.
My laptop will power on but I'm still getting a blinking light on the caps lock button and a black screen.
The laptop was running hot. I cleaned the dust from the fan area. The battery is bad. I checked the volts on the charger which was 43v - bought a new charger that's 18.5 v. I wiped the ram and started with one and moved to different positions. I now have a black screen with the cap lock key blinking blue non-stop and the f12 key led light is constantly on orange. What I should try next and what does the cap lock led blinking without stopping means - is that a code or have a significance?
I recent did Microsoft and Lenovo updates and I have lost the On-Screen Volumn display. Not the Volumn icon in the task bar, I lost the display that shows the volumn going up or down on the screen. The video support suggested installing Power Management but this did not work. I have tried uninstalling and reinstalling the audio drivers, also did not work.
Recently, I turned on the on screen indicators for caps and num lock by accident when trying to get the pop-up window to stop opening every time I hit one of the buttons. Now I don't know how to disable it, and it's a pain while playing games.
Solutions tried: Going to preference, there is no "On-Screen Display Tab" Going to run the regedit.
Hp pavilion dv7-6c64nr entertainment PCCore i7Windows7After i switch on its has black screen, caps lock blinking 3 times, function key f12 wifi signal on. But the machine always running (I can hear the sound).
I am just entering some numerial data and found out that there is no num lock key on the new designed keyboard. There is also no description about this in the manual. Do I need to set something to use?
I have a problem with two T400 thinkpads. The first T400 was dead when I bought it ( suspected graphics card ) . Well I managed to get this laptop to boot up. The screen was black but I found by chance that if shine a lamp or light on the screen it is working. Now being able to see what I was dooing on the screen faintly. So I updated the bios & that did not fix the problem but I was well happy about finding out this trick. I then added 8Gb kingston ram which works with my other T400 laptops. I installed Win 7 ultimate. The laptop is working fine. No issues just extreamley dark screen almost black "but working" Very strange indeed.
T400 - TWO
Now the second laptop was working fine. But I was swapping the parts with the non working laptop to determine the problem. Now I have two T400 laptops with a dark almost black screen. But over about a month working on them I am making progress. I am determind not to give up on these computers. This is not like fixing or repairing a computer. More like rezerecting a computer. I did not intend to spend so much time on these laptops but I have found a common problem that effects a lot of people. I would love to know why a working laptop when re- assembled gives an almost black screen & still works. Normally I would just buy a new motherboard & bin the defekt one. What I need is some command codes to try to make the screen brighter. Is this planned obsiletion or just a graphic defekt myth. Because after throwing away more supposidly dead motherboards with a graphic defekt than I can count. I am starting to think that if I get the brightness back on my computers I will have sloved a major black screen problem. It is not the graphic processor. I have been playing fifa 14 with a lamp shining on the screen. It played fine, not jumpy ,no colour stripes just very dark.
Today I was surfing the internet on my Lenovo t500 ubuntu. After a Kernel Panic ( i'm not sure it was that some text on my screen ). I shutdown the computer and restart it but the screen stayed black. Not even Thinkpad logo at boot. The fan is working the lid are working, the keyboard too. So after trying to fix it i went on a walk while the computer was on and when I got back I heard the ubuntu noise when it start. So i try but terminal to run music and it works but the screen stay black. I tried to remove RAM, 10 times shutdown without battery or plug. Nothings worked. I cannot try without another screen yet..
Lenovo T400 to install Windows XP on it..It previously worked fine with windows 7 and 8.1.so it boots in windows XP preinstall screen, it formats hdd and like usual installation automatically restarts after that BUT its black screen, lights and sounds show that it works and goes to next screen BUT the screen is still black. Powering down and turn on again is not showing any screen picture. Opened it removed Bios battery, turned up after few on and off it starts it reset bios.
So now there is picture and it goes on the next screen of windows instalation like normal, after installing devices and stuff it automatically restarts like usual BUT it has NO screen again, black screen, lights and sounds again show that its loading windows end instalation screen but no picture on the screen. Reset BIOS again, it starts normaly and this time it shows BSoD with code 0x7B, after BSOD Black screen again..Maybe its a BIOS setting?!? tried installing with drivers for AHCI and tried installing without drivers for Compatible , what else can it be? Updated the bios to latest version, same result. To say it again - it works fine with other windows, but XP must be installed
I'm running Win 7, and I have the most up-to-date drivers from the Lenovo site. I have turned on loudness equalization, but it has not worked. This is an across-the-board problem. What I mean by that is, this problem persists regardless of the application, which I happen to be using. For instance, I use Media Player Classic: Home Cinema to watch movies. If the volume is at 0%, as I begin adjusting it upward, the volume level rises. However, as I reach about 70%, the volume stops increasing. There are audio adjustments w/in the application to boost the volume, but they serve to provide minimal effects. Overall, the volume is incredibly low. If you're sitting more than a few feet away from the laptop, it is inaudible.
I've been recovering from a virus and am trying to get things back to the way I had them and I've noticed something different about the volume meter. First off my volume indicator was missing, when I hit the volume buttons nothing showed up on screen. I realized I needed to install the energy mangement driver and did so. The issue is that I don't care for the appearance of the volume meter. It has yellowish green buttons and the volume increases and decreases by 5 with one press of the volume buttons. The volume meter that I had previously was a white white bar that increased and decreased by 1 each time I hit a volume button. I liked this design a lot better. I'm trying to figure out what version of the energy management driver I had previously that would allow my volume and brightness indicators to be the white bar instead of they yellowish green buttons. My machine type is 2359 and model is CTO with Windows 7 64 bit.
